Create a database
InfluxDB Clustered is currently only available to a limited group of InfluxData customers. If interested in being part of the limited access group, please contact the InfluxData Sales team.
influxctl database create command
to create a database in your InfluxDB cluster.
If you haven’t already, download and install the
influxctl database createcommand and provide the following:
influxctl database create \
--retention-period 30d \
--max-tables 500 \
--max-columns 250 \
- Retention period syntax
- Database naming restrictions
- InfluxQL DBRP naming convention
- Table and column limits
Retention period syntax
--retention-period flag to define a specific
for the database.
The retention period value is a time duration value made up of a numeric value
plus a duration unit. For example,
30d means 30 days.
A zero duration retention period is infinite and data will not expire.
The retention period value cannot be negative or contain whitespace.
Valid durations units include
- m: minute
- h: hour
- d: day
- w: week
- mo: month
- y: year
Example retention period values
3d: 3 days
6w: 6 weeks
1mo: 1 month (30 days)
1y: 1 year
30d30d: 60 days
2.5d: 60 hours
Database naming restrictions
Database names must adhere to the following naming restrictions:
- Cannot contain whitespace, punctuation, or special characters.
Only alphanumeric, underscore (
_), dash (
-), and forward-slash (
/) characters are permitted.
- Should not start with an underscore (
- Maximum length of 64 characters.
InfluxQL DBRP naming convention
In InfluxDB 1.x, data is stored in databases and retention policies. In InfluxDB Clustered, databases and retention policies have been merged into databases, where databases have a retention period, but retention policies are no longer part of the data model. Because InfluxQL uses the 1.x data model, a database must be mapped to a v1 database and retention policy (DBRP) to be queryable with InfluxQL.
When naming a database that you want to query with InfluxQL, use the following naming convention to automatically map v1 DBRP combinations to a database:
Database naming examples
|v1 Database name
|v1 Retention Policy name
|New database name
Table and column limits
In InfluxDB Clustered, table (measurement) and column limits can be
configured using the
Default maximum number of tables: 500
Each measurement is represented by a table in a database. Your database’s table limit can be raised beyond the default limit of 500. InfluxData has production examples of clusters with 20,000+ active tables across multiple databases.
Increasing your table limit affects your InfluxDB cluster in the following ways:
Default maximum number of columns: 250
Time, fields, and tags are each represented by a column in a table. Increasing your column limit affects your InfluxDB cluster in the following ways:
